CVE-2026-8602Network attack vector

Unauthenticated sensor-reading injection via HTTP GET

Published May 19, 2026 · Updated May 19, 2026

Missing authentication in ScadaBR 1.2.0 allows remote attackers to inject arbitrary sensor readings through HTTP GET requests. The interface accepts attacker-supplied sensor values without verifying an authenticated identity; CISA does not disclose its endpoint or parameter names. Network access to the web application is sufficient, and the resulting false telemetry compromises monitoring integrity without a reported data-disclosure path.
